2 Claims. (01. 2201) This invention relates to improvements in elevated tank construction and, more especially, an elevated steel tank supported by posts.

My invention is applicable to an elevated tank including a cylindrical shell with a lower ring of plates joined by vertical seams. The principal feature of my invention is the provision of supporting posts, each including a tangentially arranged flat part, for example, the web of an H-beam, extended upwardly to form the butt straps for the vertical seams in the lower ring of the shell.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings Figure 1 is a view in side elevation of the post; 20 Fig. 2 is a view taken as indicated by the line 2 of Fig. 1; Fig. 3 is a view taken as indicatedby the line 3 of Fig. 1; Fig. 4 is a vertical sectional view; Fig. 5 is a view in front elevation of one of the posts with a part in section; and. Fig. 6 is a view from the inside of the shell looking outwardly toward one of the posts.

As shown in the drawings, the tank includes a cylindrical shell, indicated in general by 10. As here shown, this includes a lower ring of plates 10 joined by the vertical seams 11. There may be one or more rings above the lower ring, as indicated by 12. It is contemplated that there be one post for each vertical seam 11 in the lower ring, although if desired, there may be fewer or more posts.

13 indicates-a curved bottom for the shell 10.

One of the posts is indicated, in general, by 14. As here shown, this post comprises an H-beam with'the web 14 and flanges 14 The 40 post is arranged with the flanges lying substantially radially with respect to the cylindical shell 10. This causes the flat part, or web 14 of the post to lie tangentially with respect to the circumference of the shell. The web 14 is extended upwardly by joining onto the same at 15 the rectangular plate 14. This plate, therefore, virtually forms anextension of the web .14, and it also serves as a butt strap for the vertical seam 11 in the lower ring of plates 10, 50 10 tachment to-the post, placing the load substantially over the center of the post, and also furnishes a butt strap for the joint.

As here shown, I prefer to apply inner butt straps it to the vertical seams.

This construction furnishes a very good at- It will be noted that the butt strap 14 forming the extension or continuation of the web 14 is somewhat wider than the web. The flanges 14 extend upwardly to the line 15, and the side portions of the plates 14 are extended 5 downwardly somewhat below this line, as indi-- cated by 14 14 These lower portions are somewhat widened to provide bent ears 14 that may serve for the attachment thereto of supporting braces or rods. Considering the por- 05 tions 14 as being parts of the butt strap 14, it will be seen that this butt strap and the flanges 14 of the post overlap somewhat.

17, 17 indicate reinforcing angle irons on the outside and inside, extending from the lowerqo edge of the parts 14. upwardly beyond the upper ends of the flanges 14 The outer ones extend almost to the top of the butt straps 14. 18, 18 indicate plates attached to the outer angle irons 17 to hold th balcony supports 19.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended. claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

1. An elevated steel tank, including; a cylindrical shell with a lower ring of plates joined by vertical seams; a curved bottom of the shell; and a pluralityof posts supporting the shell, each of said posts having a fiat part substantially tangentially arranged with respect to the shell, said flat part being extended upwardly to form a butt strapfor one of the vertical seams in the lower ring of the shell.

2.-An elevated steel tank, including; a cylindrical shell with a lower ring of plates joined by vertical seams; a curved bottom for the shell; and a plurality of posts supporting the shell, each of said posts including an H-beam with the flanges substantially radially arrangedand, with the web thereof extending upwardly,to form a butt strap for one of the vertical seams in the lower ring of the shell.
